Wang Gan looked at him and shook his head. Although this five-element divine iron was considered precious, it was really nothing in his opinion. When Ao Gu refined the Zhuxian Sword, the main material was Chaos Stone. All the remaining materials were precious divine iron materials. Wang Gan remembered that many five-element divine irons were melted at that time. I'm afraid that there were dozens of divine irons of this level at that time, and they were all collected by Ao Gu's Qingling Cave Heaven. "The last treasure is very precious. It was taken out by Master Xingyuan of Xingdou Palace. It was a wisp of primitive Taoist energy. There is no need for a little girl to say more about the preciousness of the primitive Taoist energy. Everyone can bid as much as a gift!" The woman in the purple robe appeared in her hand a fist-sized crystal ball in her hand. A wisp of dragon and snake-like air flow kept rotating and wandering, and an inexplicable aura emanated from the crystal ball.
